humming noise at 40 mph evo
Hi, i cant seem to identify the problem on my evo. I have a video on the bottom.. It is a whining noise at around 40mph but goes away if ur going 45mph and up... I would cruise at 40mph and accelerate and decelerate and i can hear it whining... I replaced both front wheel bearings with oem, i just changed all the fluids- trans-tcase- rear diff. The rear wheel bearings i havent changed out yet. I have searched and cant seem to find the problem. I have searched t case whine but it sounds nothing like that.
My thoughts- Rear wheel bearings, t case? I had notice that my rear axle seal is barely leaking in the rear. Any input is helpful!

I've had my evo for about 8 Months and have heard all sorts of groans, clunks, whirl noises coming from under it and as a new buyer I have always felt i need to find out exactly what it is and fix it but ... it was only the other day when I got underneath it to do an oil change is when i noticed how many linkages and moving parts that is packed under there, so when you start to hear a noise do you strip everything down and replace lots of parts or do you just let it play out and see what happens or if it gets worse and then you can alot easier identify the part thats going south. The later is what I have decided to do. In the mean time just enjoy the thing.

My mustang made the same noise after swapping my ring and pinion. Never had an issue. You'll get used to it. I have no interior. You should hear mine LOL
I am going to more or less assume my rear end always made noise but Was always dampened by the rubber bushings. I highly doubt swapping bushings would do anything To change the lash in the differential. I could be wrong though, just making an educated guess.
I would check for metal shavings on the drain plug. Just in case.

i just changed the rear diff and t case fluid and no metal shavings and also had the car inspected for my t case and it wasnt it... The guy said it was normal and that he heard way worse noises in evos than mine and that i shouldnt worry about it but figured its my rear diff bushings and ams mustache bar delete
